Exeter Resource (XRA) Reports Positive Metallurgical Test Results at Caspiche

March 22, 2011 9:16 AM EDT
Exeter Resource Corporation (AMEX: XRA) reports positive results from its metallurgical test program on sulfide mineralization at its Caspiche project.

Highlights of testwork conducted by independent laboratories include:
  • Reduction Roasting: Testwork by both Outotec (Sweden) AB and Technip USA (Inc) reduced arsenic levels in concentrate samples to 0.2% arsenic, a level considered commercially acceptable (without penalties) in most smelter contracts.

  • High Temperature/Pressure Oxidation: Testwork solubilised 99% of the copper, leaving the arsenic as the residue mineral scorodite. Leaching of the residue yielded gold dissolutions that averaged 96%. These results strongly suggest that high quality cathode copper and gold-silver bullion can be produced from a plant that uses pressure oxidation to treat concentrates, and the recoveries will be very high.
